This is the "cog" that drives the hydraulic suspension pump on W116, W123, W201 16V, and W126 chassis with self leveling suspension
This is the part that more often than not gets lost when the SLS pump is removed from an engine for a long period of time. If you are trying to return the system to original after someone has removed the pump you most likely will need this part.
